Apprently following entry is misleading  "Support for GCS is reported to userspace via HWCAP_GCS in the aux vector AT_HWCAP2 entry." from https://docs.kernel.org/next/arch/arm64/gcs.html

https://github.com/torvalds/linux/blob/master/arch/arm64/include/uapi/asm/hwcap.h seems to have HWCAP_GCS (1UL << 32).
